Insulation in rennovation...am I correct?

Quick background...I live in a split level home. In January I will start a project in which I will gut the garage (living space above and adjacent). Once gutted I am sectioning off the back 1/3 and adding a home office. My place was to add R19 on the exterior wall, frame along the cinderblock wall and add R13 to all interior walls and R30 to the ceiling. I read that unfaced with a 6 mil vapor barrier is more effective. Am I correct on my plan?

gonefishing , Ponch is correct. even in the ceiling it will have an effect with R-30 in a 2x6 ceiling beam bay. in that case I install r-19 unfaced and then go over it in the other direction with the R-30 keeping the sides of the insulation tight. The Idea is to not expose the sides of the insulation or else it cuts down on its performance.
